I deployed an application on Heroku. I'm using the free service. Quite frequently, I get the following error. <pre class="prettyprint"><code>PG::Error: ERROR: out of memory </code></pre> If I refresh the browser, it's ok. But then, it happens again randomly. Why does this happen? Thanks. Sam Kong

<code>heroku restart</code> simply helped me though

PG::Error: ERROR: out of memory on Heroku

I deployed an application on Heroku. I'm using the free service.

Quite frequently, I get the following error.

PG::Error: ERROR:  out of memory

If I refresh the browser, it's ok. But then, it happens again randomly.

Why does this happen?

Thanks.

If you experience these when running queries, your queries are complicated or inefficient. The free tier has no cache, so you're already out there.

If you're getting these errors otherwise, open a support ticket at https://help.heroku.com
